πολύκτονος
From LSJ
νὺξ βροτοῖσιν οὔτε κῆρες οὔτε πλοῦτος, ἀλλ' ἄφαρ βέβακε, τῷ δ' ἐπέρχεται χαίρειν τε καὶ στέρεσθαι → starry night abides not with men, nor tribulation, nor wealth; in a moment it is gone from us, and another hath his turn of gladness, and of bereavement | Starry night does not remain constant with men, nor does tribulation, nor wealth; in a moment it is gone from us, and to another in his turn come both gladness and bereavement
Russian (Dvoretsky)
πολύκτονος: состоящий во множестве убийств (σίνος Aesch. - v. l. πολυκτόνος).
